Grinding machine equipment is one of the commonly used tools in modern industry. Large grinding machine tools can improve the efficiency and accuracy of industrial production, and are an indispensable industrial production tool for users. Grinding machine products are divided into many different types, and each type of grinding machine can provide different types of services. Internal cylindrical grinder is also a common industrial grinder used to improve the production quality of processed workpieces. In terms of use, it focuses on processing products with inner hole surfaces and end faces formed by cylindrical, conical, or other geometric lines. The operation difficulty of the internal grinder is relatively high, and we need to understand the precautions for using the equipment before use.
The main content of CNC internal grinding machine includes the methods of use and the types of products mainly processed by the equipment. Today we will explain its main uses, operating procedures for automatic internal grinding machines, and precautions for use. The difficulty of using an internal grinding machine is relatively high, and we need to pay attention to some operational difficulties. Operators must operate slowly when cutting to prevent accidents caused by low sensitivity of the equipment; When measuring workpieces with plug gauges or instruments, the grinding wheel should be pulled out of the workpiece and stopped steadily to prevent sudden automatic operation of the grinding wheel. Measure the workpiece with a plug gauge. When pulling out the plug gauge, it must be stable and not affect the measurement accuracy. When replacing or modifying the grinding wheel, the general safety regulations of the grinder should be followed to improve the safety level of use.
CNC internal grinding machines can be divided into ordinary internal grinding machines and universal internal grinding machines. Ordinary grinding machines have a wide range of applications because they have been on the market for a long time and are used by many users. The cost performance ratio of ordinary internal grinding machines is relatively high, and the price is also reasonable. The application range of universal internal grinding machine is also wide, which can grind the internal cylindrical surface of various shaft and sleeve workpieces on the basis of ordinary internal grinding machine. The application scope of the universal grinder is still expanding, and it is believed that there will be many occasions in the future that require the use of this equipment.
